JOHN B. HART AND EMERY H. WALKER, OF HOLYOKE, MASSACHUSETTS.

DEVICE FOR CLEANING CUT RAGS AND SAVING SMALL RAGS OF THE SAME.

SPECIFICATION forming part of Letters Patent No. 311,186, dated January 27, 1885.

Application filed April 9, 1884. (No model.)

To all whom it may concern:

Be it known that we, JOHN B. HART and EMERY H. WALKER, citizens of the United States, residing at Holyoke, county of Hampden, Massachusetts, haveinvented a new and useful Device for Cleaning Cut Bags and Saving Small Bags of the Same, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

Figurel is a perspective view of our invention. Fig. 2 is a diagram showing in side elevation and section the leading details of the device; and Figs. 3, 4, 5, 6, and 7 are enlarged views of certain parts in detail.

The object of our invention is to provide a treatment for rags and similar materials used in paper-manufacture and kindred arts, by which said rags, after being cut, will be separated in a degree from foreign substances without so great a waste of small rags as is common to processes nowiiin, use. We attain these objects by the mechanism illustrated in the accompanying drawings, wherein similar letters refer to like parts throughout the several views.

In Fig. 1, A is a frame or guide containing an endless belt, B, passing over the roll 0,

and over suitable rolls (not shown) on other portions of the frame. The roll 0 is attached to a shaft, D, having at one end the tight and loose pulleys E. for the purpose of transmitting motion tosaid'roll G. The shaft D passes through suitable bearings in the posts F F. Below the roll 0, and attached to the posts F F by pins G G or in any other proper manner, is the tray H, having at its opposite end an apron, I, and having its bottom formed of open-work J, (more fully described hereinafter.) At the end of the tray H,which bears the apron I, are two posts, K K, supporting the camshaft L, and a second roll-shaft, M. The cam-shaft L contains two cams, N N, and a pulley, O, as shown. This pulley O is connected by the belt P with a similar pulley, Q, onthe first roll-shaft, D, and by the connection described the revolution of the first roll causes revolution of the cams.

On the tray H are the projections R, resting on the cams N, whereby the revolution of thecams produces a vibratory motion of the tray H. The second roll, S, carries an endless belt similar to that on roll 0, previously described, and receives motion in a suitable manner.

The arrangement of the various parts described and the direction of their motion are shown in Fig. 2.

The action of the mechanism described is as follows: The cut rags to be operated upon are delivered onto the belt or carrier B, moving in the direction shown, and are carried forward over the roll G and dropped into the tray H. This delivery to the tray is gradual and dependent upon the velocity of the roll. The rags, after striking the upper end of the tray, gradually slide toward its lower extremity, impelled by gravity and the vibratory motion of the tray. The bottom of the tray is formed of open-work made of bars, as shown in Fig. 8, or wires or rods, as shown in Fig. 4., arranged parallel to each other, or laid in different directions, crossing or interlacing, as indicated in Figs. 5 and 6; or the openings may be perforations in a continuous sheet, as shown at Fig. 7. As the rags pass along the bottom of the tray the dust and other impurities work to the bottom and fall through. Small rags also pass through and are deposited below,where they may be collected and used, whereas without this device they would remain mixed with the larger pieces until blown out by a duster, when by their small size they would pass through the meshes of the screen and be lost.

The object of the apron I is to carry the rags fairly onto the second belt-carrier,which moves them to the desired point of delivery.

Having described our invention, what we desire to claim and secure by Letters Patent 1. In a rag-cleaning machine, the combination of an endless delivery belt or apron, an endless receiving belt or apron, and an interposed tray having an openwork or fora-minous bottom, substantially as set forth.

2. In a rag-cleaning machine, the combination of an endless receiving belt or apron, an endless delivery belt or apron, an interposed inclined tray having an open-work or perforated bottom, and a cam-shaft having cams for vibrating said tray, substantially as set forth.

3. In a rag-cleaning machine, the combine V at the lower end of said tray, substantially as set forth.

5. The combination, in a rag cleaning and separating machine, of carrier-rolls G and S, 15 and carriers, tray H, apron I, canis N, projeo tions R, and pulleys E, Q, and O, substantial} y as set forth.
